More than 10 million people in the United States saw politically divisive ads on Facebook that the company said were bought in Russia in the months before and after last year’s US presidential election.

Facebook will turn over copies of political ads purchased by Russian sources to congressional lawmakers, who are investigating the country's potential interference in the 2016 US presidential election.

Spain's Data Protection Authority has issued a 1.2 million euro fine against Facebook after it found three cases when the company collected data without informing users, as required by European Union privacy laws.
